10 Times Doctor Who Accidentally Predicted Our Future
4. Margaret Thatcher
The Sixth Doctor was an advisor to Margaret Thatcher in the 1980s stage play Doctor Who: The Ultimate Adventure (and its audio adaptation). Much like Winston Churchill before her, she doesn't feel like the sort of politician the Doctor would hang out with, but there we are.
However, it wasn't the Doctor who predicted Thatcher's rise to power. It was a line ad-libbed by Nicholas Courtney as the Brigadier which accidentally predicted Thatcher's election as Prime Minister in 1979, and lent weight to the theory that the UNIT stories take place in the 1980s.
During the final episode of 1975's Terror of the Zygons, as the Loch Ness Monster advances towards the Thames, the Brigadier takes a call from the Prime Minister. "Oh, absolutely understood, madam. No public announcement. Yes, madam. Discreet action. Discreet but resolute."
In 2005, Russell T Davies made his views on Mrs. Thatcher perfectly clear, by having Harriet Jones commit a sci-fi version of the sinking of the Belgrano. The Tenth Doctor ensured that Jones be removed from office in retaliation.
